NOx emissions can be controlled through engine operation with lean homogeneous air/fuel mixtures. This emission control approach precludes the need for exhaust gas recirculation (EGR) and secondary ...

SAE Transactions, Vol. 104, Section 3: JOURNAL OF ENGINES (1995), pp. 2093-2103 (11 pages) Lean mixture combustion might be an important feature in the next generation of SI engines, while diluents ...

Plenty of myths surround the workings of internal-combustion engines. One is that an engine running lean—meaning too much air is going into the cylinders—tend to run hot. Jason Fenske of Engineering ...

If you have a lemon, make lemonade." Rather than complain about all the newfangled computer/smog technology, wise hot rodders are finding that they can adapt much of it to make their cars run faster.
